CVE-2025-14601 in vsDesk
Summary
by MITRE • 08/20/2026
An OS command injection vulnerability in vsDesk allows an authenticated attacker with administrative privileges to execute arbitrary operating system commands due to insufficient input filtering. An attacker can exploit this flaw to disrupt web server operations, expose sensitive data, or potentially achieve full server compromise.
Apply patch from vendor https://vsdesk.ru/ . Versions 14.0101 and on have the patch.

The vulnerability identified in vsDesk represents a critical OS command injection flaw that stems from insufficient input validation within administrative functions of the application. Although exploitation requires an attacker to possess authenticated administrative privileges, this requirement does not mitigate the severity of the risk given the high level of trust typically associated with such accounts. The core technical failure lies in the processing of user-supplied data where special characters or command separators are not adequately sanitized before being passed to underlying operating system commands. This lack of proper input filtering allows an attacker to inject arbitrary shell commands into legitimate application processes, effectively bypassing intended security controls and gaining direct access to the server's execution environment.
From a technical perspective, this flaw aligns with CWE-78 Improper Neutralization of Special Elements used in an OS Command commonly known as OS Command Injection. The vulnerability likely exists in modules that handle system configuration, file management, or other administrative tasks where input is directly concatenated into command strings without using safe APIs like parameterized execution functions. By exploiting this weakness, a malicious actor can manipulate the context in which commands are executed, potentially leveraging the privileges of the web server process to run arbitrary code with elevated permissions on the host operating system.
The operational impact of this vulnerability extends far beyond simple service disruption. An attacker who successfully exploits this flaw can execute any command supported by the underlying shell environment. This capability enables a range of malicious activities including but not limited to reading sensitive configuration files, exfiltrating database contents containing user credentials and personal data, modifying application logic, or installing persistent backdoors for long-term access. In severe cases, full server compromise is achievable, allowing the attacker to pivot into internal network segments, escalate privileges further, or deploy ransomware and other destructive payloads against critical infrastructure hosted on the compromised system.
To mitigate this risk, immediate action must be taken by applying the vendor-provided patch available from vsdesk.ru. Organizations should verify that their instances are running version 14.0101 or later which includes the necessary code fixes to address the input validation deficiencies. In addition to updating software, administrators should enforce strict principle of least privilege for administrative accounts and implement robust web application firewall rules to detect and block command injection patterns even if similar vulnerabilities exist in other components. Regular security audits and penetration testing focused on authentication bypasses and injection flaws are recommended to maintain a strong defensive posture against such threats aligned with MITRE ATT&CK techniques related to Command and Scripting Interpreter abuse.
